Abstract
A swirl-flow forming body includes a through-hole; a jetting port that is formed on an inner periphery facing the through-hole; a fluid passage that allows fluid to be discharged into the through-hole via the jetting port so as to form a swirl flow that generates negative pressure for applying suction to a target object; and a flange portion that is formed so as to protrude from the inner periphery, the flange portion allowing passage of fluid to which suction is applied by the negative pressure while preventing the fluid discharged via the jetting port from flowing out of the through-hole towards the target object. The inner periphery is formed so as to guide the fluid discharged via the jetting port, in a direction away from the target object, to be discharged from the through-hole.
